5 Claims.

My invention relates to containers such as bottles and the like, andparticularly to containers designed for holding pharmaceutical orchemical preparations in liquid form.

It is well known that in pouring a liquid from a bottle a drop of theliquid always adheres to the neck when the bottle is tilted back to itsvertical position, and, since the drop hangs from the outer edge of theneck, when the bottle is righted the drop usually runs down the outsideof the bottle. Furthermore, when the bottle is placed upright, theliquid remaining on the edge of the neck usually spreads over the top ofthe neck of the bottle, forming a film of liquid thereon. Thischaracteristic of bottles or containers is extremely objectionable whenthe liquid is of a corrosive or sticky nature or tends to harden aredangerous to handle if the liquid is corrosive and present an extremelyunsightly appearance when streaked with colored or sticky liquid. Whencaps are applied to receptacles of this type the film of liquid on thetop of the neck tends to corrode or rust the cap and threads,contaminating the liquid and rendering it extremely difficult to removeth cap after the bottle has stood for some time.

Containers for paint, varnish, lacquers and so forth, which tend toharden on drying, are also subject to this objection, and for thisreason paint cans are not ordinarily provided with threaded necks,although threaded closures provide considerable advantages over closureof other types for use on containers having liquids therein which tendto evaporate.

Attempts have been made to overcome the disadvantages inherent inbottles formed with rounded upper edges at the top of the neck byforming an outwardly turned tapering-lip which is considered to reducethe amount of liquid adhering to the edge of the bottle. However, evenwith such construction the outlet opening in the neck of the bottle iscircular so that the liquid in passing over the edge of the neck flowsover a relatively large portion of the circumference thereof, wettingthe same and causing the liquid to flow laterally over the top of theneck when the bottle is righted so that corrosion and sticking of thecap is not materially reduced.

Furthermore, 'it is common practice to provide containers withinternally threaded necks formed with an externally located pouringspout,

the container being closed by an externally threaded plug or closurefitting within the neck so that the pouring spout is always exposed.How-- ever, this construction is not adapted for use on bottles orglassware wherein the pouring spout is liable to be injured duringshipment or handling of the bottle.

. In accordance with my invention, the fore- 5 going objections anddifiiculties presented by the use of bottles and containers of the priorart are overcome and a container provided which is formed with anexternally threaded neck adapted to'receive and engage an internallythreaded cap 10 formed with complementary threads, the neck beingprovided with a pouring spout designed to be covered by the closuremember and formed to confinethe liquid being discharged from thecontainer to a limited area of the neck of the 16 container. Theprovision of a pouring spout serves to prevent the flow of liquid downthe outside of the bottle or laterally about the top of the neck whenthe bottle is righted.

In the present invention the container is pro- 20 vided with a threadedneck having a pouring spout formed thereon. However, in the presentinstance the neck is threaded substantially to the top thereof and thepouring spout may be located in whole, or' in part, within the threadedportion 25 of the neck.

One of the objects of my invention is to prevent the fiow of liquid downthe exterior of the neck or laterally over the top of the neck of acontainer. 30

Another object of my invention is to prevent the corrosion and stickingof threaded caps to the necks of containers.

A further object is to provide a container having an externally threadedneck formed with a 35 pouring spout thereon.

Another object is to provide a container having a pouring spout adaptedto be covered by the closure for the receptacle.

A further object of my invention is to provide 40 a bottle adapted tocontain pharmaceutical or chemical preparations in liquid form which isfree from the difiiculties and disadvantages inherent in bottles formedwith circular outlet openings. as

Another object of my invention is to provide a container having a neckthreaded substantially to the top thereof and having a pouring spoutformed in the neck.

These and other objects and features of my in- 50 vention will appearfrom the following description of preferred forms thereof, in which Fig.1 is a plan view of a preferred: structure as applied to a bottle;

Fig. 2 is a vertical sectional view of a bottle drical throughout with acap thereon taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective of a bottle having the neck thereof formed asshown in Figs. 1 and 2, with the cap removed.

Figs. 4 and 5 respectively, show a side and a perspective of analternative form of structure embodying my invention.

In the form of the 1, 2, and 3, of the drawing the container is in theform of a bottle 2 having a neck 6 provided with a. thread 6. A shoulder8 may be formed on the: neck of the bottle below the thread to limit thedownward movement of the cap if desired. The thread 6 at the point In isinterrupted for a suflicient distance to permit the formation of apouring spout E2. The pouring spout is formed by a contraction of thematerial from which the neck is formed at the points it on either sideof the spout l2 and within the space it in the interrupted portion ofthe thread e. The interior of the neck of the container is substantiallycylinthe portion id thereof and is formed with depressed portions 56 oneither side of the pouring spout it. The pouring spout thus constitutesan angularly formed lateral projection on the neck of the containerwhich serves to confine the liquid as it is poured therefrom.

I prefer to construct the pouring spout with inwardly and sloping lowersides so asto cause liquid to drain back into the bottle from thepouring spout when the bottle is righted after pouring liquid therefrom.

The top of the neck of the container is preferably flat, so that theentire top of the neck lies within a single plane. The neck thusprovides a flat surface against which a packing member may bear to sealthe container against leakage during handling and shipping thereof.

A cap i formed with a continuous thread it is adapted to engage thethread 6 on the neck of the container. Packing member 22 is carried bythe cap in the top thereof so that upon screwing the cap down on to theneck of the container the packing member will engage the top of the neckto seal the container against leakage.

By this arrangement, the container is formed with a pouring spout withinthe threaded portion of the neck thereof and at the same time the usualthreaded cap employed for closing, such containers may be used. Theouter extremity of the pouring spout i2 is located in alignment with, orwithin the inner diameter of the thread t, as determined by the verticalportion of the neck. of I the bottle. For this reason the pouring spoutdoes not interfere in any way with the application or, the removal ofthe cap from the con tainer. When the cap is applied the po spout iswholly covered by the cap so that injury thereto in handling thecontainer is avoided.

In the alternative form oi the invention, illustrated in Figs. 4 and 5,the thread 6 is formed so that it begins at one side of the pouring sideit and terminates at the opposite side thereof. The pouring spout isthus located between the ends of the thread and does not interfere inany way with the application of a cap thereto. In this form of theinvention the outer extremity of the pouring spout i2 may be positioned'so that it extends into the thread on the cap forming in efiect a.portion of the thread 5. This construction has the added advantage thatthe pouring spout l2 may extend beyond the vertical portion of the neckd and into alignment with the outer However, the edge may inventionillustrated in Figs.

diameter of the thread 6. For this reason the pouring spout it may beformed somewhat larger than in the construction illustrated in Figs. 1,2, and 3, without interfering with the application of the cap to theneck of the bottle.

In the drawing I have illustrated bottles in which the edge of the topof the neck is fiat. of course be rounded or bevelled if desired, but inany case I prefer that the top of the neck should be entirely in asingle plane so as to provide a suitable surface against which thepacking member may engage to seal the container against leakage.

While I have illustrated and described two alternative forms of myinvention, it will be apparent that the invention is not limited tothese. particular structures or to the use thereof on bottles or glassreceptacles, but may be applied to other containers whether formed ofmetal, resinous compositions or other material. It should therefore beunderstood that I do not wish to confine my invention to the preferredforms thereof herein illustrated and described except as defined by theclaims.
